ASUNCION, Paraguay (AP) - A presidential candidate in Paraguay has died in a helicopter crash.

Spokesman Johnny Villalba of Paraguay's airport authority says Lino Cesar Oviedo was returning from a political rally Saturday night in northern Paraguay when the pilot encountered bad weather. Also killed in the crash were the pilot and Oviedo's bodyguard.

Villalba said Sunday that the cause will be investigated by his agency.

Oviedo was 69, a retired general and former army chief who was running for president in April's elections as leader of an opposition party, the National Union of Ethical Citizens. It's the third largest party in Paraguay.
